The RaggDoll Motorsports Charge Cooler & Tertiary Heat Exchanger System is a high-performance intercooler upgrade for the Porsche 718 Cayman and Boxster, engineered specifically for 2017–2024 2.0L and 2.5L turbocharged models.
Designed to support 600+ horsepower, this air-to-water charge-cooling system dramatically lowers intake air temperatures, reduces heat soak, and delivers consistent, repeatable performance under aggressive street and track conditions — without requiring engine removal.
Built exclusively for the Porsche 718 (982) platform, this is not a universal intercooler adaptation. It is a purpose-engineered charge cooler solution designed around Porsche’s factory cooling architecture.
The Porsche 718 uses a liquid-to-air intercooler (charge cooler) rather than a traditional front-mount air-to-air intercooler. While effective at stock power levels, the factory system becomes overwhelmed as power increases.
Common issues include:
These problems are amplified with ECU tuning, turbo upgrades, hot climates, and track use.
The RaggDoll Motorsports system solves this by increasing intercooler coolant volume and heat-rejection capacity, allowing intake air temperatures to remain stable even under sustained boost.
This upgrade adds a high-capacity Tertiary heat exchanger to the factory charge-cooling circuit, dramatically improving the system’s ability to shed heat.
By lowering intercooler coolant temperatures, the system:
The heat exchanger is strategically positioned for maximum airflow, utilizing high-pressure frontal air rather than compromised side locations, without sacrificing OEM functionality.
This system is ideal for Porsche 718 Cayman & Boxster owners who are:
If you’re searching for a 2017 Porsche Cayman intercooler, 718 Boxster intercooler, or Porsche 718 charge cooler upgrade, this system was engineered specifically for that purpose.
Professional installation is recommended.
No engine removal is required for installation.
ECU tuning is strongly recommended to take full advantage of the improved cooling efficiency and to optimize performance safely.
Vehicle Compatibility:
From charge cooling and turbo systems to fueling and tuning support, RaggDoll builds complete performance ecosystems—not one-off upgrades.
More cooling.
More consistency.
More confidence.
Built differently — because performance demands it.
Liza & most of the time Vince is amazing...lol. Nah, kidding, these guys are awesome folks to deal with. I purchased their Stage 2 turbo, turbo inlet, intercooler, engine tune, and high pressure fuel pump for my 2018 2.5L Boxster GTS and they're products and service have been top notch throughout the entire process.
Raggdoll Motorsports set up two dyno sessions for my Porsche Turbo S. The Porsche touts a 4.0-liter built engine and head work facilitated by Sam at ByDesign. Also has the XR ByDesign turbo kit with all the supporting mods. The first session the PDK kept transitioning out of manual mode. During the second session a boost leak at the throttle body boot ended the session early. We managed 812 hp on a Mustang dyno at only 20 psi of boost.
The people behind RaggDoll Motorsports have been in the game for a very long time and really know their stuff. They have a passion for modifying cars and are enthusiasts before anything else.
I purchased a RENNEN turbocharger for my 718 T. I had a special request, which was to get the turbine housing coated with Swain Tech white lightning thermal barrier coating and RaggDoll accommodated without hesitation even though it was something new for their team.
Hey All! Shout out to Liza and @Raggdolls718. Amazing customer service, product knowledge and a top quality product. Liza went out her way to accommodate my tight timeframe and the level communication and level of detail shared was amazing.
I purchased the Raggdoll Series One turbocharger upgrade and the turbo inlet upgrade from RMS for my Porsche 718 Cayman GTS and was very pleased with both the products and the customer service from RMS!
